Wis. Stat. § 807.07
This section does not confer jurisdiction on the court to hear an appeal in a criminal case when the appeal is not timely. Scheid v. State, 60 Wis. 2d 575, 211 N.W.2d 458 (1973). Sub. (2) applies only at the trial court level. It does not confer appellate jurisdiction on the supreme court when an appeal is first mistakenly taken to the circuit court. State v. Jakubowski, 61 Wis. 2d 220, 212 N.W.2d 155 (1973). Mere retention of an appellant's brief prior to making a motion to dismiss is not participation in the appeal and does not constitute a waiver of an objection to jurisdiction. Prior holdings to the contrary are overruled. State v. Van Duyse, 66 Wis. 2d 286, 224 N.W.2d 603 (1974). When a claimant timely appealed an adverse worker's compensation decision in good faith but erroneously captioned the appeal papers, the trial court abused its discretion by dismissing the action. Cruz v. DILHR, 81 Wis. 2d 442, 260 N.W.2d 692 (1978). Sub. (1) does not apply to petitions to appeal under s. 808.10. First Wisconsin National Bank of Madison v. Nicholaou, 87 Wis. 2d 360, 274 N.W.2d 704 (1979). The court of appeals erred in failing to exercise discretion under sub. (1) to permit an amendment of a notice of appeal. Northridge Bank v. Community Eye Care Center, 94 Wis. 2d 201, 287 N.W.2d 810 (1980). Sub. (2) applies to actions for review under ch. 227. Shopper Advertiser v. DOR 117 Wis. 2d 223, 344 N.W.2d 115 (1984). Sub. (2) permits transfer of a case when the action was originally filed in a court lacking subject matter jurisdiction or when the action was filed in a court of improper venue. Shopper Advertiser, Inc. v. DOR, 117 Wis. 2d 223, 344 N.W.2d 115 (1984), 81-1409. '"Return" is a long-standing term of art that refers to the official record of the body whose decision is being reviewed and that must be filed with the reviewing court in a certiorari action. Because sub. (1) provides that "return" must be "duly made" before the respondent's participation in the action waives jurisdictional objections, when respondent's answer was filed before return was made to the circuit court, the answer did not waive its right to contest personal jurisdiction. Bergstrom v. Polk County, 2011 WI App 20, 331 Wis. 2d 678, 795 N.W.2d 482, 09-2572. The default remedy when a court lacks competency is dismissal under s. 802.06(8). However, when the lack of competency derives from an improperly venued case, the court may transfer the case to a proper venue under sub. (2) so long as the error arose from a good faith error. DWD v. LIRC, 2016 WI App 21, 367 Wis. 2d 609, 877 N.W.2d 620, 14-2928.
